中文摘要 | 本文主要採貝氏決策法於設定適性測驗級分標準。研究採三參數 Beta-binomial 分配和事先編列之決策損失表以決定級分標準並控制測驗級分得分的人數。本研究並採用最佳逐次法則來推估適性施測的級分標準。最後,研究以八十七年度推薦甄試國文及自然兩學科能力測驗電腦閱卷試題原始總分的分配為例,採貝氏決策法來決定適性測驗級分標準表。 |
英文摘要 | This study suggested using the Bayesian decision method to classify mastery levels for the Basic Achievement Tests given by the College Entrance Examination Center (CEEC). The Bayesian method takes into account raw score istributions as well as test reliability for decision making; the method also allows restricted quota of examinees passing a given mastery level by using a prespecified loss table or function. This study used the scores on the multiple-choice items in the 1998 Chinese and Natural Science Basic Achievement Tests as examples to illustrate the use of the Bayesian method for assigning mastery levels. The Bayesian method can also be generalized to classify mastery levels in adaptive tests. This study also used the optimal sequential rule to estimate the mastery levels at every stages of adaptive tests for the two Tests. |
